Sorry, I can not understand the error.

What did you do?
What did you expect to happen?

[myagami]

In map generation both from png and the default algorithm, the each corner is always land even if the corner is designated as a water tile.
And I tried  in same condition simutrans v122.0 for does not this bug.

The top left most tile certainly used to always be land regardless of the map using the algorithm. I wasn't aware if it happened with png.

I don't know if it was all corners or not.

Beach generation was broken. Fixed in r10363

This uncovered another problem: Since beach generation is from left top to right bottom, beach would grow to the bottom right, or one get very few beaches (like right now).
